BMPROVEMENT IN FlREd-PROOF MANSARD ROOFS.

Specification forming part of Lettrrs Patent No. 142,793, dated Sepiunber 16, 1873; application iiled December 4, 1872.

5,' detached views, representing the methody Aof securing the tiles to the slitting-bars; Fig.

6, an elevation, showing the method ot' coustructing the inside partitions; and Figs. 7, 8, and 9, detached views, 4representing the details of construction of the partitions.

Similar letters of reference in the accompanying drawings denote the same parts.

The object of my invention is to provide for the publie an improved mode of constructing French roofs, so as to render them lire-proof withoutaddin g to their cost or detraeting from their lightness and strength; to which end the invention consists, first, in the improved method of constructing such roofs of common gas-pipes connected by sockets; and, secondly, in the details of construction, as hereinafter more specifically set forth and claimed.

` In the drawings, AA' represent the rafters, which may be straight or curved, according to the design selected for the roof; B B', the horitontal pieces corresponding to the polevplates, purlins, and ridge-pieces; C C', up-

rights to support the structure; and D 1),tiebeams to secure the various parts in their proper position. All the parts are constructed of common iron gas-pipev or similar'tubing,

Vconnected by screw-sockets a a in the manner usually employed by plumbers and gas-litters,

. as clearly shown in Figs. 1 and 5.V The. frame'- work of the root` being thus constructed, iron slating-bars E E are attached to the rafters and secured in position by means of bolts with conntersunk heads, as represented lin Fig. 3. The tiles F are attached to the bars E, pret'- erably, by means of hooks f catchingaronml the upper edge ofthe slitting-bars, i n the manner shown in Figs. 1, 2, 4, 5. When metallic tiles are employed the hooks may, if preferred, be cast or formed as a part of the the itself.

In order to 4render the upper part of the building as nearly as possible indestructible by fire, I construct the partitions by attaching grooved iron supporting-bars G to the sides of the uprights O C, as shown in Figs. 6, 7, 8, 9, and placing tiles Il. upright in the grooves. Spaces are left between the tiles, and the whole is then plastered over. Figs. 7 and 8 represent a single partition, and Fig. 9. a double partition, thus constructed. The saine mode of constructing the partitions may be adopted in any part of the buildin".

It will be observed that illy improved mode of constructing this class of roofs'requires no special adaptation of the materials to the purpose, except such as can be made on the spot by any gas-fitter with the ordinary tools of his trade, The materials, too, are all in common use, and are, therefore, abundant, convenient, and cheap, so that my new mode of construction involves no additional delay or expense. 1f desired, a water-pipe may be connected to the tubular frame A A', and the lat-A ter may be perforated, so as to throw sheets or streams'of water upon the roof 1n case of tire.

I claim as my inventioni 1. The arrangement of theinclined or curved tubes A A', when provided with slatin g-bars E, in combination wi th horizontal tubes B B', npright-tubes O O', tie-tubes D, and couplingpiece a, as and for the purpose set forth.

2. The improved manner of securing the slating to the slating-bar E by means ot' the headed hook f, which passes through an orice in the slate, and is curved -so as to catch over and around the slating-bar E, substantially as and for the purpose set forth.

3. The tire-proof partition constructed substantially as shown in Fig. 6, and covered with plaster or other suitable covering, substantiall y as described, for the purposes speci- JosrAII W. KENNEDY.
